118. The World Wildlife Fund has declared that global warming, a phenomenon most scientists agree to be caused by human beings in burning fossil fuels, will create havoc among migratory birds by altering the environment in ways harmful to their habitats.
(A) a phenomenon most scientists agree to be caused by human beings in burning fossil fuels,


(B) a phenomenon most scientists agree that is caused by fossil fuels burned by human beings,


(C) a phenomenon that most scientists agree is caused by human beings’ burning of fossil fuels,


(D) which most scientists agree on as a phenomenon caused by human beings who burn fossil fuels,


(E) which most scientists agree to be a phenomenon caused by fossil fuels burned by human beings,

关于这题的提问有很多，我看得眼花缭乱，但是还是没有真正理解

答案选C。

我想问：C中蓝色字体代表是什么成分？定语从句做宾语还是其它？

             C中红色字体代表什么成分？定语从句做宾语吗？

            以前上课笔记上说that作定语从句充当宾语时可以省略，作定语从句充当主语时不能省，作宾语从句时不能省，作同位语从句时不能省。但是可能是我比较笨，C选项的成分我判断不出，请NN简单作答。（我只想知道这两个部分分别作什么成分）

其实应该是most scientists agree that a phenomenon is caused by human beings’ burning of fossil fuels,但a phenomenon要做global warming的同位语,所以才提上来的吧~
